Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Figure 1 shows the implementation process of the timing start control method for household appliances provided by the embodiment of the present invention. For the convenience of description, only the parts related to the embodiment of the present invention are shown, and the details are as follows:

In step S1, the standby time of the household appliance is counted and detected, and the air humidity of the environment where the household appliance is located is detected in real time.

In step S2, when the standby time is not less than the first standby reference time, the household appliance is controlled to start running for a preset time and then shut down and enter the standby state.

Wherein, the first standby reference time is a preset time for weighing whether the household appliance satisfies the timing start operation condition. For example: suppose the first standby reference time is ts1, the preset reference humidity value is ds1, the standby time is t, the current air humidity is d, and the preset time is T; when t≥ts1, and d<ds1, it indicates the standby time Once the condition for controlling the start-up of the household appliance has been reached, it is necessary to control the start-up of the household appliance for a preset time T before shutting down and entering the standby state. And if the standby time is less than the first standby reference time, the household appliance is not controlled to start and run, and the household appliance remains in the standby state.

In step S3, when the standby time is not less than the second standby reference time and the detected current air humidity is not less than the preset reference humidity value, the household appliances are controlled to start running for the preset time and then shut down and enter the standby state.

Wherein, the second standby reference time is a preset time for measuring whether the household appliance satisfies the timing start operation condition, and the preset reference humidity value is the preset air humidity used for measuring whether the household appliance meets the timing startup operation condition value. The above-mentioned first standby reference time is not equal to the second standby reference time. Considering that household appliances tend to get wet when the air humidity is high, the condition for controlling the start-up of household appliances in step S3 is that the standby time is not less than the second standby reference time, and the current air humidity is not less than the preset reference humidity value. For example: suppose the second standby reference time is ts2, the preset reference humidity value is ds1, the standby time is t, the current air humidity is d, and the preset time is T; when t≥ts2 and d≥ds1, it indicates the standby time and the current air humidity have reached the conditions for controlling the start-up and operation of the household appliances, then it is necessary to control the start-up and operation of the household appliances for a preset time T before shutting down and entering the standby state. And if the standby time is less than the second standby reference time and/or the detected current air humidity is less than the preset reference humidity value, the household appliance is not controlled to start and run, and the household appliance remains in the standby state.

When the household appliance is an air conditioner, in order to prevent long-term deposition of oil in the compressor and debris deposition in the pipeline of the air conditioning system, in the above steps S2 and S3, control the household appliance to start and run for a preset time before stopping and entering standby mode. In the step of state, it is necessary to control the key components such as compressor, electronic expansion valve, four-way valve and fan in the air conditioner to start operation.

When the household appliance is a split-type air conditioner, the step of detecting the air humidity of the environment where the household appliance is located in real time in the above step S1 is specifically: real-time detection of the indoor environment of the indoor unit of the split-type air conditioner and the split-type air conditioner The outdoor environment where the outdoor unit is located performs air humidity detection to obtain the current indoor air humidity and the current outdoor air humidity. The current indoor air humidity is the real-time air humidity of the indoor environment where the indoor unit of the split-type air conditioner is located, and the current outdoor air humidity is the real-time air humidity of the outdoor environment where the outdoor unit of the split-type air conditioner is located. When the current indoor air humidity is greater than the current outdoor air humidity, the current indoor air humidity is taken as the current air humidity; when the current indoor air humidity is lower than the current outdoor air humidity, the current outdoor air humidity is taken as the current air humidity; when the current indoor air humidity is equal to the current outdoor air humidity When the air humidity is selected, the current indoor air humidity or the current outdoor air humidity is used as the current air humidity.

For example: assume that the second standby reference time is ts2, the preset reference humidity is ds1, the standby time is t, the current air humidity is d, the current indoor air humidity is dn, the current outdoor air humidity is dw, and the preset time is T.

When dn>dw, then d=dn, if t≥ts2 and dn≥ds1, it indicates that the standby time and the current air humidity have reached the conditions for controlling the start-up and operation of household appliances, and it is necessary to control the preset time T for start-up and operation of household appliances Then stop and enter standby mode.

When dn<dw, then d=dw, if t≥ts2 and dw≥ds1, it indicates that the standby time and the current air humidity have reached the conditions for controlling the start-up and operation of household appliances, and it is necessary to control the preset time T for start-up and operation of household appliances Then stop and enter standby mode.

When dn=dw, then d=dn or dw, if t≥ts2 and dn and dw≥ds1, it indicates that the standby time and the current air humidity have reached the conditions for controlling the start-up and operation of household appliances, and it is necessary to control the start-up and operation of household appliances After the preset time T, it will stop and enter the standby state.

Further, the above-mentioned relationship between the second standby reference time and the first standby reference time is as follows:

ts2=ts1×(1-d)

Wherein, ts1 is the first standby reference time, ts2 is the second standby reference time, and d is the current air humidity. When the current indoor air humidity is greater than the current outdoor air humidity, the current indoor air humidity is taken as the current air humidity; when the current indoor air humidity is lower than the current outdoor air humidity, the current outdoor air humidity is taken as the current air humidity; when the current indoor air humidity is equal to the current outdoor air humidity Air humidity, the current indoor air humidity or the current outdoor air humidity is used as the current air humidity.

For example: suppose the first standby reference time is ts1, the second standby reference time is ts2, the preset reference humidity value is ds1, the standby time is t, the current air humidity is d, the current indoor air humidity is dn, and the current outdoor air humidity is dw, the preset time is T.

When dn>dw, then d=dn, ts2=ts1×(1-dn); if t≥ts2 and dn≥ds1, it indicates that the standby time and the current air humidity have reached the conditions for controlling the start-up of household appliances, then It is necessary to control the household appliances to start and run for a preset time T and then stop and enter the standby state.

When dn<dw, then d=dw, ts2=ts1×(1-dn); if t≥ts2 and dw≥ds1, it indicates that the standby time and the current air humidity have reached the conditions for controlling the start-up of household appliances, then It is necessary to control the household appliances to start and run for a preset time T and then stop and enter the standby state.

When dn=dw, then d=dn, ts2=ts1×(1-dn), or, d=dw, ts2=ts1×(1-dw); if t≥ts2 and dn and dw≥ds1, it indicates If both the standby time and the current air humidity have reached the conditions for controlling the start-up of the household appliance, it is necessary to control the start-up of the household appliance for a preset time T before shutting down and entering the standby state.

To sum up, the embodiment of the present invention detects the standby time of household appliances by timing and detects the current air humidity in real time; when the standby time is not less than the first standby reference time, it indicates that the standby time has reached the condition of timing start operation, It will control the household appliances to start running for a preset time and then stop and enter the standby state; and when the standby time is not less than the second standby reference time, and the detected current air humidity is not less than the preset reference humidity value, it indicates that the standby time and The current air humidity has reached the condition of timing start and operation, and it will also control the household appliances to start and run for a preset time and then stop and enter the standby state, so as to realize the timing start and run for a period of time when the household appliances stop running and standby for a long time Time to avoid the problem of shortened service life of household appliances due to internal debris deposition and component aging.

Based on the above-mentioned timing start control method, the embodiment of the present invention also provides a timing start control device for household appliances. Figure 2 shows its module structure. For the convenience of description, only the parts related to the embodiment of the present invention are shown , as detailed below:

The timing start control device includes a standby time detection module 100 , an air humidity detection module 200 and an electrical appliance operation control module 300 .

The standby time detection module 100 performs timing detection on the standby time of the household appliance, and the air humidity detection module 200 detects the air humidity of the environment where the household appliance is located in real time;

When the standby time detected by the standby time detection module 100 is not less than the first standby reference time, the electrical appliance operation control module 300 controls the household appliance to start running for a preset time and then shut down and enter the standby state;

When the standby time detected by the standby time detection module 100 is not less than the second standby reference time, and the current air humidity detected by the air humidity detection module 200 is not less than the preset reference humidity value, the electrical appliance operation control module 300 controls the household appliance After starting and running for a preset time, stop and enter the standby state;

Wherein, the first standby reference time is not equal to the second standby reference time.

If the standby time is less than the first standby reference time, the appliance operation control module 300 does not control the household appliance to start running, and the household appliance remains in the standby state.

In addition, if the standby time is less than the second standby reference time and/or the detected current air humidity is less than the preset reference humidity value, the appliance operation control module 300 does not control the household appliance to start running, and the household appliance remains in the standby state.

Since the air humidity detection module 200 detects the air humidity of the environment where the indoor unit and the outdoor unit are located, the air humidity detection module 200 may specifically include an air humidity sensor (used to detect the current Indoor air humidity) and an air humidity sensor (used to detect the current outdoor air humidity) arranged on the outdoor unit.

For example: assume that the second standby reference time is ts2, the preset reference humidity is ds1, the standby time is t, the current air humidity is d, the current indoor air humidity is dn, the current outdoor air humidity is dw, and the preset time is T.

When dn>dw, then d=dn, if t≥ts2 and dn≥ds1, it indicates that the standby time and the current air humidity have reached the conditions for controlling the start-up and operation of household appliances, and the appliance operation control module 300 is required to control the start-up of household appliances After running for a preset time T, stop and enter the standby state.

When dn<dw, then d=dw, if t≥ts2 and dw≥ds1, it indicates that the standby time and the current air humidity have reached the conditions for controlling the start-up of household appliances, and the appliance operation control module 300 is required to control the start-up of household appliances After running for a preset time T, stop and enter the standby state.

When dn=dw, then d=dn or dw, if t≥ts2 and dn and dw≥ds1, it indicates that the standby time and the current air humidity have reached the conditions for controlling the start-up and operation of household appliances, and the electrical appliance operation control module 300 is required Control the household appliances to start and run for a preset time T and then stop and enter the standby state.

For example: suppose the first standby reference time is ts1, the second standby reference time is ts2, the preset reference humidity value is ds1, the standby time is t, the current air humidity is d, the current indoor air humidity is dn, and the current outdoor air humidity is dw, the preset time is T.

When dn>dw, then d=dn, ts2=ts1×(1-dn); if t≥ts2 and dn≥ds1, it indicates that the standby time and the current air humidity have reached the conditions for controlling the start-up of household appliances, then It is necessary for the electrical appliance operation control module 300 to control the household appliance to start running for a preset time T and then shut down and enter the standby state.

When dn<dw, then d=dw, ts2=ts1×(1-dw); if t≥ts2 and dw≥ds1, it indicates that the standby time and the current air humidity have reached the conditions for controlling the start-up of household appliances, then It is necessary for the electrical appliance operation control module 300 to control the household appliance to start running for a preset time T and then shut down and enter the standby state.
